Instructional Ideas

• Add this video to a high school chemistry unit on acids and bases
• Create a worksheet with the three example problems on it so students can follow along with the video
• Flip your chemistry classroom by assigning this video as a homework exercise

Pros

• The video begins with an overview of the concepts being covered
• Presenter walks step-by-step through three different problems involving the disassociation of diprotic acids

Cons

• The video may not capture the engagement of all learners
• The presenter's handwriting is a little sloppy at times, but is still legible
